Query Parameters

​
limit
integer
default:"50"
Page size — number of transactions to return per request. Maximum 200.
​
cursor
string
Opaque pagination cursor. Omit on the first request; on subsequent requests, pass the next_cursor value from the previous response to fetch the next page. When the server returns next_cursor: null (equivalently has_more: false), you have reached the end of the pool’s history.
​
instruction_type
string
Filter by instruction type (e.g. SwapExactIn, Deposit). See the Instruction Types table below for possible values. When set, only transactions matching this type are returned. Pages may contain fewer than limit results.
​
cluster
string
default:"mainnet-beta"
Solana cluster — mainnet-beta or devnet.

​
Response

​
data
array
Array of transaction records on this page, ordered by most recent first.
​
next_cursor
string | null
Cursor to pass as ?cursor=... on the next request to fetch the following page. null when there are no more transactions (end of history).
​
has_more
boolean
true if more transactions are available beyond this page, false if this is the last page.
